Which function describes the arithmetic sequence shown?

Mathematics
1 answer:
Vedmedyk [2.9K]3 years ago
5 0

Answer:

D

Step-by-step explanation:

The n th term of an arithmetic sequence in functional notation is

f(x) = a₁ + (x - 1)d

where a₁ is the first term and d the common difference

d = - 7 - (- 5) = - 7 + 5 = - 2 and a₁ = - 5, thus

f(x) = - 5 - 2(x - 1) = - 5 - 2x + 2 = - 2x - 3 → D

Logarithm 2. The alkalinity of a fluid (pH) can be modeled in terms of its hydrogen ion concentration (H^+,measured in moles/lit
makkiz [27]

ok. We are given the following equation:

ph=-\log (H)

Where:

\begin{gathered} P=\text{ alkalinity} \\ H=\text{ hydrogen ion concentration} \end{gathered}

Since we are asked to determine "H" we will solve for "H" in the equation. To do that we will first multiply both sides by -1:

-ph=\log (H)

Now, we will use the following property of logarithms:

\log _aB=c\rightarrow B=a^c

Applying the property and having into account that:

\log (H)=\log _{10}(H)

We get:

10^{-pH}=H

Now we substitute the given value of "pH = 4.5":

10^{-4.5}=H

Solving the operation:

0.000032=H

Therefore, the hydrogen ion concentration of the fluid is 0.000032
